I gave a try to the brand new 2.6.27 kernel on my ADS5121 evaluation board:
* FEC support is not in, though it was quite easy to add FSL patches
from 2.6.24.6 and have the ethernet working
* If I turn on any USB support, the board resets itself as soon as
the USB driver is loaded. Without USB, I can get to a prompt.
Funny that the software reset is not working, but this bug is
actually able to sw reset the board...
* PCI seems not to be working, but I need to test it more. The fact
that FSL needed to patch 2.6.24.6 in order to get PCI working
makes me think it's needs some work.
This is bad because I wanted to incorporate some newer patches, like the
PWM one, but kernel 2.6.24.6 is too backward in time, while 2.6.27 is
too forward for FSL patches...

I've applied some 3 patches from John Ribgy to add 5121 PCI support.
These are intended for .28, but should be clean against .27.
They are:
powerpc/fsl: Hide MPC5121 pci bridge.
powerpc: 83xx: pci: Remove need for get_immrbase from
mpc83xx_add_bridge.
powerpc/5121: Add PCI support.
And can be found in:
git.kernel.org:/pub/scm/linux/kernel/git/galak/powerpc.git powerpc-next
